Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

open access: yesAdvanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

PSEUDOSTENOSIS OF THE RENAL ARTERY [PDF]

open access: yesAmerican Journal of Roentgenology, 1966
Pseudostenosis or spasm of the renal artery was seen in approximately 2 per cent of selective renal arteriograms in 159 patients. It is believed to be caused by the mechanical irritation of the catheter or of the injection. It occurs for the most part in younger patients whose renal arteries are otherwise normal.
